There are tools and algorithms mature enough to add value in almost any industry and you do not need a Math Ph.D to learn Deep Learning. In this talk, I will briefly paint a picture of the exciting world of Deep Learning and then explain Deep Learning concepts using Convolutional Neural Networks as a base.

This process should give everyone insight into how search engines work that can then be applied even when using production-ready systems like Elasticsearch.
